An 85-year-old Nepalese man wants to reclaim the title of being the oldest person to ever climb Mount Everest.

Min Bahadur Sherchan previously held the world record in 2008 but lost it in 2013 when 80-year-old Japanese climber Yuichiro Miura scaled the peak.

He now wants to reclaim the title by climbing the 8848m Himalayan peak during a window of favourable conditions next month.

"I want to be the oldest person to scale Everest again to be an inspiration for humankind, a boost for the elderly people and an encouragement for youths," Mr Sherchan told AP on Wednesday from his Kathmandu home.

"It will be a message for everyone that age is no obstacle to achieving their dreams."

Mr Sherchan's high-altitude home gives him an advantage over most other climbers as it makes him unsusceptible to the ailments that plague many others who attempt to climb the world's highest mountain.

He had originally planned to regain his title in 2015, but an earthquake which triggered an avalanche killed 19 people at Base Camp a day before he arrived.
